BELT-CONVEYER MECHANISM.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed October 31, 1904. Serial No. 230,658.

To all whom it may concern:

Be it known that I, WiLLIAM E. BEE, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Belt-Conveyor Mechanism, of which the following is a specification, reference being had to the accompanying drawings,which form a part of this specification.

My invention has for its object certain new and useful improvements in belt-conveyer mechanism; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a view in vertical section, showing features of the device in elevation. Fig. 2 is a plan view of the same. Fig. 3 is a view in vertical section through portions of the conveyer mechanism. Fig. 4 is a view on the line 4 4, Fig. 3, showing parts in vertical section and other features in end elevation. Fig. 5 is a view in section on the line 5 5, Fig. 3. Fig. 6 is a view in section on the line 6 6, Fig. 3. Fig. 7 is a view in horizontal section on the line 7 7, Fig. 6.

One of the essential features of my invention is to provide concentrator mechanism for belt conveyers which shall be practically self-alining, which shall only need oiling at long intervals; also, to construct a concentrator for belt conveyers wherein there shall be no leakage or dripping of oil or grease upon the conveyer-belt or upon any material carried thereby; also, to provide bearings for various portions of said mechanism made self-oiling, oscillatory, and self-adjusting or self-locating.

My invention also includes the general features of construction herein shown and described.

I carry out my invention as follows:

In the drawings, a represents a stand or other suitable support upon which are mounted bearings b b, carrying the shaft 0 of the carrier roller or rollers (1, upon which the conveyer-belt 6 travels. To said stand or support a are also secured bearings f f, carrying the shaft g of the supporting or return roller or rollers h. The shafts c and g may be provided with one or more rollers, as may be preferred. Troughing-rollers are indicated at i i, which may be set at any desired angle to the shaft 0. Each of the bearings b is provided with an oil well or case, (indicated at j,) the same being preferably formed integrally with the corresponding bearing. Said oil case or well is provided with a spindle (indicated at preferably cast into the oil-case, at one end thereof, as indicated at Z. Each of the troughing-pulleys "L is cast with a sleeve or hub (indicated at m) to fit over the corresponding spindle 7n, the roller and the hub being connected by a web a. The oil-case is spaced from the hub or sleeve to form an oil-chamber, as shown. The upper end of the oil-case is formed with an opening about the hub of the roller, and it will be seen that oil may be supplied to said oil-chamber up to a level with the base of the said opening, as indicated by the horizontal lines in said oil-chamber. Oil maybe supplied when needed to the oil-chamber through the opening in the oil-case or otherwise, as may be preferred. The oil may be passed from said oil-chamber to lubricate the corresponding spindle k in any suitable manner, as at the lower end of the hub. The hub of the troughing-roller may be readily removed from the spindle when it may become necessary to do so. It will be seen that oil cannot drip over said oil-chamber and that it is capable of containing a sufficient amount of oil to last for a long period of time without refilling.

To oil the extremities of the shaft 0, my in vention contemplates providing an oilchamber p, provided with a sleeve 9 to receive the corresponding end of the shaft 0, the end of the shaft extending into the upper portion of the oil-chamber formed within the oil-case p, a ring 1" being mounted upon the end of the shaft and depending into the oilchamber. Said oil-chamber may be supplied with oil in any suitable manner, as througha feed-inlet 8. About the sleeveq I provide an outer case 25, provided with interior shouldered sockets to, the sleeve g being provided with spurs 'u to fit into said sockets. It will be perceived that since the spurs 4) fit into the shouldered sockets u the corresponding sleeve will be prevented from slipping off from the end of the shaft. The bearing is preferably formed with contact-points w, the bearings being spaced, preferably, from the case t between said points. The case if, it will be perceived, is made adjustable within the bearings or oscillatory therein, the same being held in given position by means of a setscrew as, passing through the bearing. The construction of the oiling mechanism with the adjustable case p is preferably made the same for the extremities of both the shaft 0 and g and are herewith shown and lettered the same, with the exception that the setscrew as for the oiling mechanism of the shaft 0 is at the top of the bearing, while the setscrew in the mechanism for oiling the lower bearing is at the bottom of the bearing.

It will be perceived that the lower ends of the spindle 7c and of the hub m are submerged in the oil within the oil-chamber, so that the parts will be self-oiling.

It will be perceived also by reference to Fig. 2 that the troughing-rollers have their centers in the same vertical plane as the longitudinal center of the shaft 0. While the concentrator-rollers i are shown projecting upward and outward and at an angle to the shaft 0, they may extend horizontally within the scope of my invention.

The upper ends of the spindles 7c, it will be perceived, are covered by the end of the adjacent hub m.

What I claim as my invention is 1. In a conveyer-belt mechanism the combination of a bearing, an oil-case forming an oil-chamber supported upon said bearing, a spindle supported upon said bearing within said oil-chamber, and a troughing-roller provided with a sleeve or hub engaged upon said spindle.

2. A conveyer-belt roller having in combination therewith an upwardly projecting oil-case forming an interior oil-chamber open at its upper end and provided with a spindle projecting upward through said oil-chamber,

said roller constructed with a sleeve or hub engaged upon the spindle, said oil-chamber arranged to contain a supply of oil to submerge the lower extremities of the spindle and of the hub.

3. A conveyer-belt mechanism having in combination an oil-case forming an interior oil-chamber, a spindle projecting through the oil-chamber, a support for the oil-case and spindle, and a troughing-roller constructed with a sleeve or hub engaged upon said spindle, said oil-case spaced from said sleeve.

4. In a conveyer-belt mechanism the combination of a bearing, an oil-case supported upon said bearing open at its outer end, a spindle supported upon the bearing, and a troughingroller constructed with a sleeve or hub engaged upon said spindle, said oilcase spaced from said sleeve to form an oilchamber about the sleeve.

5. In a conveyor-belt mechanism the combination of a supporting roller, bearings therefor, an oil-case supported upon each of said bearings, a spindle supported upon each of said bearings, and a troughing-roller constructed with a sleeve or hub engaged upon each of said spindles, the supporting-roller and the troughing-rollers being in the same vertical. plane.

6. A conveyer-belt roller having in combination therewith an oil-case forming an interior oil-chamber open at its outer end, a spindle within the oil-chamber, and a support for said oil-case and spindle, said. roller constructed with a sleeve or hub projecting through the open end of the oil-case and engaged upon said spindle.

7. In a belt-conveyer mechanism a fixed support provided with an oil-case forming an oil-chamber, and with a spindle, and a trough ing-roller provided with a sleeve or hub projecting into said oil-chamber to receive said spindle, said oil-case spaced from said sleeve or hub.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
